    my MacAfee live safe is now installed until aug. 2018, can I download avast now or wait until aug? Thanks.

    • February 28, 2018 at 3:08 PM by info

      You can wait or install it now, it is up to you.

    This site onlinethreatalerts.com seems to be trustworthy, and I would follow they advice to use just one AV program at a time to avoid slowing down the computer. Besides of RAM and HDD space any AV program run a lot of CPU activity, worm up the device, draw dust, overuse the electricity and wear down the device's flash memory or the computer HDD in case of use of multiple AVP.

  • February 12, 2018 at 9:12 AM by an anonymous user from: Oakville, Ontario, Canada

    Thanks for the information on Total AV, they really make themselves look good.

    ZAI currently use Windows 10 with Windows Defender, Super Antispyware and Malwarebytes all sort of together, they dont usually scan atthe same time.

    I used superantispyware Before Windows 10 had any protection to speak of, now I use Windows Defender as my core system and SuperAntispyware that seems to from time to time find and come up with stuff to delete or quarantine, and MalwareBytes.

    The reason for Malwarebytes is that once I seem to have had an intrusive virus and purchased Malwarebytes which seemed to have deleted the malware attack and they also claim to have ransom protection.

    I find my computer "Asus I7 with 12GB Ram and plenty of spare HD about 200GB extra" to be slow. Am I doing all the right stuff?

    Compare the free antivirus software on this website (onlintthreatalerts.com), PCMAG.com, and Tomshardware.com to help you decide which one to use.

  • January 19, 2018 at 4:08 PM by an anonymous user from: Memphis, Tennessee, United States

    What is the safest free antivirus program to use on my laptop? I had one for a while, and actually paid for it to be on my computer for two years. It lasted a few months and then it said I had to pay again and that it had run out. It still scans for issues, but I can't fix them without paying again, and I put a lot of money to begin with.

    • January 31, 2018 at 3:46 PM by an anonymous user from: Muncie, Indiana, United States

      Don't pay for antivirus software. Checkout reputable websites like PCMAG.com and Tomsguide.com in the "free antivirus" search results list for recommendations. Some of these top free antivirus software may slightly pressure to you upgrade but they don't require it to remove viruses. You can choose to stay with free by clicking on test or link at bottom of their paid offers.

    I took your advice, after being stung and strung and downloaded AVG. However, it deleted all my shortcuts and then I couldn't get into internet explorer, after which, having gone around the mountain a few times, I managed to appropriate a way that I never knew existed. I think it might just be cheaper to call in someone to fix the problems. Thank you for all you do on this website.

  • November 13, 2017 at 12:02 PM by an anonymous user from: Châtillon, Ile-de-France, France

    I was surprised to find a completely unknown antivirus as the #1 software. Thanks to your site.

  • November 9, 2017 at 11:00 AM by an anonymous user from: Helsinki, South Finland, Finland

    Hi,

    I was wondering why Total AV appeared as ranked 1 and 2 above other reputable anti-virus providers. Now I know! It's fake!

    Thanks for the advice!

    Best regards,

    Graham W.

    Sophos Home Antivirus is also free. Sophos Antivirus for Android is free.

  • October 18, 2017 at 11:47 AM by an anonymous user from: Red Deer County, Alberta, Canada

    I found the site which advertised TotalAV and found it to be "too good to be true". For such a good product as they claimed it to be, why so cheap. With a peep to the side of their page, it very clearly stated they were getting paid for promoting this product and that the ranking is based on what the companies are paying them. mmmm This should raise a red flag. Then I found your site which supported that the whole site is a fake. It is very difficult to find honest business people today. Thank you.

  • September 6, 2017 at 2:21 PM by an anonymous user from: Wentzville, Missouri, United States

    I was about to purchase TotalAV antivirus software but your information stopped me. Thanks.

  • August 9, 2017 at 7:38 AM by an anonymous user from: Belfast, Northern Ireland, United Kingdom

    Total AV is scamming ***s,they debited me £ 9.59,I had it reversed,they did not contest,what a surprise! they are still trying under slightly different names.

  • July 4, 2017 at 3:05 PM by an anonymous user from: Porto, Portugal

    I thank you for your help and recommendation as I was just about to download the fake antivirus from TotalAV. I was thinking to download the AVG but according to other people it is the same as AVAST, know I think I am going to download the Avira free antivirus.

    Thanking you for your help,

    Jose.

    I have stupidly paid $2.99 to this total AV, my laptop has not been blocked as yet but they have taken the payment from my credit card, will they keep taking payments without my knowledge and if I can successfully uninstall this threat will I still have to go through the motions of blocking and changing my card, do they steal from your account etc as this is my business account, I have a temporary block on all my account at the moment, will another antivirus get rid of it?

    • August 6, 2017 at 11:54 AM by an anonymous user from: Phoenix, Arizona, United States

      From the credit card position, you can take these steps to stop unwanted charges. I have used these myself and while it is time consuming, investing the time is worth it 🙂

      First: Contact all card companies. Ask them their procedures for blocking charges. Many of these are similar and easy to complete. Provide all identifying information about the scam company including routing numbers they use for the account they are moving your money to.

      Contact all credit reporting agencies and have watches and/or blocks put on your credit reports. At least one will have a free offer at the time you set this up. The annual fee is minimal, in my opinion, when you consider the degree of financial damage the thieves can cause.

      This is my own "out of the box" solution to block anyone gaining access to your credit information: Do not use your mother's real maiden name, the real name of your first pet or any other real answers to these questions. I use fakes and have stopped more than one attack on my credit.

      Lastly, when possible, go to your bank and get to know the people who work there. I did this and as a result had a bank friend of mine call me early one morning to ask if I had ordered appx. a thousand dollars worth of items online. She twigged on the time of day the orders were placed and the charge was flagged because of the acceptable charge limit *I* had set.

      I wish I could say whether or not any other AV software would remove the fake, I am still looking at the moment. I do hope however, my suggestions help you and anyone else who is/has been dealing with this issue. While the suggestions may seem repetitive or simplistic, it is in the simplicity, I have found, one of the easiest ways to thwart the scammers.

      I hope this helps, even a small bit 🙂

      Take care!

      Sandy.

      Not sure, but try one of the free antiviruses in the list above.

  • May 27, 2017 at 5:01 AM by an anonymous user from: Penrose, New South Wales, Australia

    Thanks for the list.I've just installed Kaspersky Internet Security 2017 after being a long time faithful user. I'm now going to try Bit Defender. Kaspersky has a lot of known issues (google it), from hanging your PC on startup until you disable it via msconfig, to causing your PC to run very slooooooooooow...Oh, and this is all on a new installed, fully updated Win7 Ultimate, i3, 8Gb, so no slow pony of a PC there.

  • May 10, 2017 at 11:24 AM by an anonymous user from: London, England, United Kingdom

    I noticed you don't have McAfee anti-virus/security software on your list. I've been using it for years and it has kept my devices 100% safe and secure... for YEARS. I recommend it unreservedly.

    In my opinion, it is better than AVG or Avast. I don't know the others on your list. I would NOT recommend readers to purchase ScanGuard.

    • May 13, 2017 at 9:21 AM by an anonymous user from: Needham, Massachusetts, United States

      McAfee sucks, I hate it.

    • May 10, 2017 at 11:29 AM by info

      McAfee is not free and ScanGuard is a fake antivirus. Remember, the article is about free antivirus software.

      • May 10, 2017 at 11:59 AM by an anonymous user from: London, England, United Kingdom

        Whoops! I didn't realize the 10 on your list are all free. I believe I pay about 49 USD per year for McAfee.

        Thank you for your blog. Very interesting. :-)

    During a web search on 5/7/17 this popped up on my android phone:

    "1 Trick to Protect Your Smartphone"

    Is your Android protected?

    Earlier this year we saw 2 million Android users in the U.S. affected by the "Hummingbird" virus, gaining access to calls, messages, etc. etc...(it goes on to say) Android Trained Developers have teamed up with renowned software provider, Scanguard to release a free Android Security Scan to users in the U.S.

    It goes on and on about how great it is and has testimonials etc.

    MY QUESTION: IS THIS A SCAM?

    It's people like me, that believe what I read, and assume it's true, that fall for these offers.

    After reading your 2013 column, I'm wondering if the "free" antivirus

    like BitDefender is still a recommended site in 2017?

    Thanks,

    Barbara

    • May 8, 2017 at 12:46 PM by info

      It is scam. Scanguard is a fake anitvirus, do not buy or use it. <a href="/article/2017/2/14/do-not-buy-scanguard-it-is-fake-antivirus-software/">Click here</a> to learn more.

      BitDefender is still recommended.

  • March 19, 2017 at 9:08 AM by an anonymous user from: Kennewick, Washington, United States

    I just went to premium on Lookout. Is it a reliable protection for my android?

    • March 19, 2017 at 11:45 AM by info

      Yes, it is reliable.
